Ascent Environmental Hazards and Hazardous Materials 4.4 HAZARDS AND HAZARDOUS MATERIALS This section evaluates the potential impacts of the Miller/Knox Regional Shoreline (Miller/Knox or park) Land Use Plan Amendment (LUPA) related to hazardous materials and public health. The evaluation provided in this section is based on public databases containing lists of known and significant hazardous waste/hazardous material sites, such as records from the State Water Resources Control Board (SWRCB) GeoTracker and Department of Toxic Substances Control (DTSC) EnviroStor. No scoping comments related to hazards and hazardous materials were received in response to the notice of preparation (NOP). 4.4.1 Environmental Setting For purposes of this section, the term “hazardous materials” refers to both hazardous substances and hazardous wastes. A “hazardous material” is defined in the Code of Federal Regulations (CFR) as “a substance or material that … is capable of posing an unreasonable risk to health, safety, and property when transported in commerce” (49 CFR 171.8). California Health and Safety Code Section 25501 defines a hazardous material as follows: “Hazardous material” means any material that, because of its quantity, concentration, or physical, or chemical characteristics, poses a significant present or potential hazard to human health and safety or to the environment if released into the workplace or the environment. “Hazardous materials” include, but are not limited to, hazardous substances, hazardous waste, and any material which a handler or the administering agency has a reasonable basis for believing that it would be injurious to the health and safety of persons or harmful to the environment if released into the workplace or the environment. “Hazardous wastes” are defined in California Health and Safety Code Section 25141(b) as wastes that: … because of their quantity, concentration, or physical, chemical, or infectious characteristics, [may either] cause, or significantly contribute to an increase in mortality or an increase in serious illness [or] pose a substantial present or potential hazard to human health or the environment when improperly treated, stored, transported, disposed of, or otherwise managed. POTENTIAL RECEPTORS/EXPOSURE The sensitivity of potential receptors in areas of known or potential hazardous materials contamination is dependent on several factors, the primary factor being the potential pathway for human exposure. Exposure pathways include external exposure, inhalation, and ingestion of contaminated soil, air, water, or food. The magnitude, frequency, and duration of human exposure can cause a variety of health effects, from short- term acute symptoms to long-term chronic effects. Potential health effects from exposure can be evaluated in a health risk assessment. The main elements of exposure assessments typically include: evaluation of the fate and transport processes for hazardous materials at a given site, identification of potential exposure pathways, identification of potential exposure scenarios, calculation of representative chemical concentrations, and estimation of potential chemical uptake. Miller/Knox Regional Shoreline Land Use Plan Amendment East Bay Regional Park District Draft Program Environmental Impact Report 4.4-1 Hazards and Hazardous Materials Ascent Environmental Sensitive receptors in the area include adjacent residences in the Brickyard Cove development as well as single-family homes in Point Richmond. Additionally, the Washington Elementary School (565 Wine Street, Richmond, CA) is located 0.21 miles north of Miller/Knox. There are no other existing or proposed schools within one-quarter mile of Miller/Knox. MILLER/KNOX LAND USE HISTORY In the vicinity of Miller/Knox land uses are characterized by a mix of open space, residential, recreational, and former industrial uses. Historical uses at Miller/Knox involved shipping, rail, and industrial activities dating back to early 1900s. Ferry Point was the western terminus of the Atchinson, Topeka, and Santa Fe, now BNSF railroad, transcontinental railroad system. For more information on the history and historic land uses at Miller/Knox, refer to Subsection 4.5.1 in Section 4.5, “Cultural and Tribal Cultural Resources.” POTENTIAL CONTAMINATION AT MILLER/KNOX Documented Sites of Contamination In California, regulatory databases listing hazardous materials sites provided by numerous federal, state, and local agencies are consolidated in the “Cortese List” pursuant to Government Code Section 65962.5. The Cortese List is located on the California Environmental Protection Agency’s (Cal EPA) website and is a compilation of the following lists: list of Hazardous Waste and Substances sites from DTSC’s EnviroStor database; list of Leaking Underground Storage Tank (LUST) sites from SWRCB’s GeoTracker database; list of solid waste disposal sites identified by SWRCB with waste constituents above hazardous waste levels outside the waste management unit; list of active Cease and Desist Orders and Cleanup and Abatement Orders from the SWRCB; and list of hazardous waste facilities subject to corrective action pursuant to Section 25187.5 of the Health and Safety Code, identified by DTSC and listed in the EnviroStor database. The SWRCB GeoTracker database includes LUSTs; permitted underground storage tanks; and spills, leaks, investigations, and cleanup database sites. The DTSC EnviroStor database includes federal and state response sites; voluntary, school, and military cleanups and corrective actions; and permitted sites. The five databases cited above identify sites with suspected and confirmed releases of hazardous materials to the subsurface soil and/or groundwater. The statuses of these sites change as identification, monitoring, and clean-up of hazardous materials progress. Typically, a site is closed once it has been demonstrated that existing site uses combined with the levels of identified contamination on-site present no significant risk to human health or the environment. The lists and databases comprising the Cortese List were reviewed to identify any active clean-up sites at or within 0.25 miles of Miller/Knox. Statuses of Cortese List sites are updated periodically and would need to be revisited before ground disturbing activities associated with the LUPA recommendations. A records search of the SWRCB and DTSC databases identified one site of documented contamination located within Miller/Knox, and 16 sites within 0.25 mile of Miller/Knox, as disclosed in Table 4.4-1 below (SWRCB 2018; DTSC 2018).

Underground storage tanks 900 Garrard Boulevard. S. were removed. Richmond, CA Regulatory Sites Listed within 0.25 mile of Miller/Knox Burmah Castrol, Inc Diesel and motor oil 0.23 Certified O&M, land use restrictions only as of August 29, 1997. This site is a 801 Wharf St. petroleum lubricant storage and transfer facility. Volatile organic compounds Richmond, CA were found in the shallow groundwater and seeping into the Richmond Channel. A remedial action plan was approved. The site was subsequently certified on February 5, 1988 but was later decertified in May 1996, when high concentrations of 1,2-dichoroethane (1,2-DCA) were found. The contaminated soil was excavated and backfilled with clean fill and bentonite slurry. Annual inspection reports conclude that the implemented remedy for the site continues to be protective of public health, safety, and the environment. Parr Richmond Terminal #1 None specified 0.05 Case completed and closed as of February 12, 2013. Investigation of potential Richmond, CA site contamination that may have occurred from activities undertaken under a former Department of Defense (World War II) lease of the site. Great Western Chemical Co. Vinyl chloride and 0.16 The site was used as a major ship construction site during World War II. The (Brenntag Pacific) 1,2-dichloroethylene primary business of the Great Western Chemical Co. was chemical distribution. 860 Wharf St. (cis) Chlorinated solvents were found in shallow groundwater on-site. Groundwater Richmond, CA monitoring and remediation activities commenced and approval for groundwater monitoring well removal was issued on November 6, 2017. Richmond Vehicle Facility – Under investigation 0.16 The site is part of the BNSF Railway system. It is a 36-acre site with 47 rail spots BNSF Railway and 3,190 vehicle bays, and railroad switching capability 7 days a week. It is 861 Wharf St. under security and restricted access. A site screening assessment was prepared Richmond, CA on April 5, 2012 and it was determined that the site was an unlikely source/contributor to the unknown chlorinated solvent plume to the south. Thus, DTSC recommended no further action at this site. Seacliff Marina Lead, mercury and 0.23 Certified O&M, land use restrictions only as of June 20, 2002.
